JOSEPH STUBBERS, OF COVINGTON, KENTUCKY, ASSIGNOR TO THE INOANDESOENT LIGHT & STOVE COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

IN CANDESCENT-LAMP FIXTURE No. 901,494. Y

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed May 14, 1906. Serial No. 316,861.

To all whom it may concern:

Be it known that I, JOSEPH STUBBERS, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Incandescent-Lamp Fixtures, of which the following is a specification.

My invention relates to an improved depending mantle and support thereof.

The improvement is adapted to be used in connection with the suspended mantle which forms the subject-1natter of a separate application filed herewith.

The features of the invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure l is a central vertical section of my improvement. Fig. 2 is a section on line 00, m, Fig. 1.

1 represents the service gas pipe supplying the burner tip with a mixture of gas and air.

2 represents the depending burner tube.

3 represents the mantle suspended therefrom.

. 4 represents a disk bracket secured upon the gas pipe. This disk bracket is preferably providedwith a depending flange 5.

6 represents screws for attaching the globe 7 to the under surface of bracket 4. The upper periphery of the globe fitting against the under surface of the bracket sub stantially prevents an upward escape of products of combustion, thereby forcing the same downward.

In the preferred form of construction the bracket is provided with a collar 9 having a threaded engagement with the service pipe 1.

10 represents a downwardly projecting collar threaded to receive the threaded burner tube 2. As the bracket is securely fitted onto the gas pipe no air can escape at this point.

I have long experimented in the effortto obtain a small globe which could be used with a suspended incandescent mantle without breaking. It has been the general experience hitherto that it is necessary to leave air passages in the globe or near the point of attachment. When I attempted to use this conventional globe, I found it necessary to use an extremely large globe for the reason that the products of combustion escaping through the air passages either in the globe or at the point of attachment to the bracket, heated one portion of the globe more than the other, so that it would frequently break.

IVith my present improvement the globes are absolutely heated uniformly and do not break. The products of combustion rise to the top or under surface of the bracket 4;, and thence in order to escape they have to flow downwardly, along the walls of the globe and so uniformly heating the top and bottom thereof.

It will be noted that this mantle has no chimney, and the heat is very intense, particularly as this improvement is primarily adapted to be used in connection with hydrocarbon burners, such as a gasolene lighting system.

With this improvement I am enabled to use small globes which are cheaper and ornamental and which serve to properly defleet the light rays downwardly.

Having described my invention, I claim 1. In combination with a depending burner tube and mantle, a depending globe around the mantle and mouth of the tube, and means of attachment closed at the top, whereby the products of combustion escape downwardly from the globe, substantially as described.

2. In combination with a depending burner tube and mantle, a depending globe around the mantle, and a solid bracket for securing said globe to the burner tube closed at the top, whereby the products of combustion escape downwardly from the globe, substantially as described.

3. In combination with a depending burner tube, mantle and globe, means for suspending the globe around the mantle, and means for closing the top of the globe against the escape of the products of combustion, substantially as described.

In testimony whereof, I have hereunto set my hand.
